High‐Entropy Sulfide Catalyst Boosts Energy‐Saving Electrochemical Sulfion Upgrading to Thiosulfate Coupled with Hydrogen Production

Angewandte Chemie International Edition, Год журнала: 2024, Номер 63(48)

Опубликована: Июль 31, 2024

Abstract Electrochemical sulfion oxidation reaction (SOR) offers a sustainable strategy for sulfion‐rich wastewater treatment, which can couple with cathodic hydrogen evolution (HER) energy‐saving production. However, the corrosion and passivation of sulfur species render inferior catalytic SOR performance, product, polysulfide, requires further acidification to recover cheap elementary sulfur. Here, we reported an amorphous high‐entropy sulfide catalyst CuCoNiMnCrS x nanosheets in situ growth on nickel foam (CuCoNiMnCrS /NF) SOR, achieved ultra‐low potential 0.25 V afford 100 mA cm −2 , stable electrolysis at as high 1 A h. These were endowed by manipulated chemical environments surrounding Cu + sites constructed “soft‐acid” “hard‐acid” adsorption/desorption sites, enabling synergistically boosted process during SOR. Moreover, developed electrochemical‐chemical tandem convert sulfions value‐added thiosulfate, providing good choice simultaneous utilization

Abstract Achieving synergistic oxidation and reduction represents a significant challenge in the field of photocatalysis. In this study, hydrothermal/in situ construction Bi atom clusters within 2 Sn O 7 /ZnIn S 4 (BSO/ZIS) heterostructures is reported. These exhibit self‐accelerating charge‐transfer mechanisms facilitated by internal electric fields bonding bridges, resulting highly efficient light absorption capabilities. X‐ray photoelectron spectroscopy (XPS) Kelvin probe force microscopy (KPFM), as well theoretical calculations, indicate that canonical induction promotion electrons holes lowers activation energy CHO* generation, allowing simultaneous CO toluene over catalyst, enhances proton‐coupling electron‐transfer processes, unique reaction mechanism. The reactant, Bi‐Bi (B‐BSO/ZIS) heterostructure achieves rate to 726.3 µmol g −1 h (99.9% selectivity) benzaldehyde 2362.0 (98.0% selectivity), which increases activity 14.6 5.7 times compared pristine ZnIn . This study underscores significance modulating photocatalytic pathway through strategic selection metal reactants, contributing rational design photocatalysts for enhanced adsorption stabilization *H.
